British Army Bivy and Groundsheet, Yes or No?

[Tank]

I used to use a IPK, then went to a reusualable space blanket but currently using a German ground mat which is just a bit wider than my bivi.

Good evening,

Many bivy bag choice topics here and I've read through most of them, but haven't found one which discusses groundsheets exclusively.

Having bought a brand new British Army bivy which I received today I have two very simple questions:

1. Do you use a groundsheet with your army bivy?
2. Is it good for extra protection or is it just unrequired extra weight?

All opinions welcome! Thanks!

1. No
2. Unrequired extra weight

Used with a basha overhead, I've never had a problem in any weather

I never used a groundsheet with mine, I just select my bivi spot carefully and pop my thermarest inside. Used this setup in the army and since leaving it and never once had any problems.

Depending on the ground conditions,I would use a groundsheet,which would be my poncho,just gives me that bit of extra room.
